| titleOfInvention | Manufacturing method of polyamide reverse osmosis membrane of high salt removal rate |
| abstract | The present invention relates to a method of manufacturing a polyamide-based membrane reverse osmosis membrane having a high salt removal rate characteristics without a large flow rate reduction compared to the conventional membrane, the polyfunctional support on the surface of the substrate coated with a microporous support is immersed in a polyfunctional amine solution In the preparation of the cross-linked polyamide reverse osmosis membrane obtained by removing the water layer on the surface by a compression method and interfacial polymerization under a polyfunctional acid halide compound solution containing an aliphatic hydrocarbon as a solvent, the support was added to distilled water containing a base before immersion of the amine solution. It provides a method for producing a reverse osmosis membrane, characterized in that for adding a step of swelling by immersion for a certain time. Such a method can achieve high salt removal rate characteristics by improving the adsorption effect of the amine solution on the support and inducing a stable interfacial polymerization reaction. |
